I know it a long way in and out from Tozus tunnel to Vikings' Cove. Now your next stop is Nepto Temple. head northwest, it is where the Nepto temple is located.
Note: do not hop on the ship, as you will always encounter a dragon which you cannot win.
- Go straight to talk to the Nepto dragon. If for some reason, you are not in the Mini state, you have to cast Mini spell again on your party members to be able to enter the dragon's mouth.
- At the end of the dungeon is a boss, Giant Rat, defeated him to retrieve the dragon eye.
- backtrack to dragon head and talk to the dragon again.
- Now go back to the Vikings' Cove and talk to the same guy who told you about the Nepto Dragon, he will give you the Enterprise.
Boss: Giant Rat
Since you are in a Mini state, the only way you can deal damage to the boss is with magic. Also this boss can use poison so having Poisona or Antidote is recommended.
Chests (3):
- Shell Helm
- Shell Armor
